Derives the [`Model`](zino_core::model::Model) trait.
# Attributes on structs
- **`#[schema(model_name = "name")]`**: The default model name is obtained by converting
the struct name to **snake-case**. You can override it by specifying the `model_name` attribute.
- **`#[schema(item_name = "name")]`**: The `item_name` attribute specifies
the corresponding field for a single model data item. Default value: **`entry`**.
- **`#[schema(item_name_plural = "name")]`**: The `item_name_plural` attribute specifies
the corresponding field for model data items. Default value: **`entries`**.
# Attributes on struct fields
- **`#[schema(ignore)]`**: The `ignore` annotation is used to skip a particular field
such that it maps to no database column.
- **`#[schema(constructor = "path")]`**: The `constructor` attribute is used to
create a new instance of the column type in `Model::new()`.
The function must be callable as `fn() -> T`.
- **`#[schema(composable)]`**: The `composable` annotation indicates that the column value
relates to a particular model. It is only valid for the data type `M`, `Option<M>` or `Vec<M>`,
where `M` is a model.
- **`#[schema(read_only)]`**: The `read_only` annotation indicates that
the column is read-only and can not be modified after creation.
It also can not been seen in the model definition.
- **`#[schema(generated)]`**: The `generated` annotation indicates that
the column value is generated by the backend and do not need any frontend input.
The column will not been seen in the model definition.
- **`#[schema(reserved)]`**: The `generated` annotation is used to mark a special column.
It will not been seen in the model definition. Built-in reserved fields:
**`created_at`** | **`updated_at`** | **`deleted_at`** | **`is_deleted`** | **`is_locked`**
| **`is_archived`** | **`version`** | **`edition`**.
- **`#[schema(auto_initialized)]`**: The `auto_initialized` annotation indicates that
the column has an automatically initialized value. Different to the `generated` column,
an `auto_initialized` value can be modified after creation.
The column will not been seen in the model definition.
- **`#[schema(inherent)]`**: The `inherent` annotation indicates that
the column value is parsed by an associated function in the model's inherent implementation.
